126 BiacksurN AND Suarp—On some New Species and Genera of Coleoptera. 
prothorace sat longioribus, obscure nec crebre punctatis, stria suturali fortiter 
impressa, basi utrinque fossa profunde impressa; femoribus crassis, tibiis anteri- 
oribus curvatis. Long. 38} m.m. 
The antennz are longer and thicker than those of L. explicandus, Sh., with 
joints seven to ten not so abruptly wider than the preceding joints. The slighter 
contraction of the thorax behind and the comparative shortness of the elytra also 
distinguish this insect. 
This species does not present exactly the generic characters attributed by Dr. 
Sharp to Lispinodes, but, as it is undoubtedly allied to L. explicandus, I place it 
provisionally in its company. By the following characters it differs:—head mo- 
derate, margined in front, and with ill-defined antennal tubercles; parts of the 
mouth fairly well developed; maxillary palpi shortish and stout, with the apical 
joint acuminate, and about equal in length to the two preceding together; mandi- 
bles well developed and prominent ; anterior coxze almost contiguous, but a rather 
conspicuous process of the prosternum enters between them. 
I unfortunately do not possess a type of Lispinus for comparison, but the well- 
defined separation of the anterior coxze in it appears to bar it against this insect. 
A single specimen occurred under the bark of a tree on the mountains near Honolulu. 
iB: 
Lispinodes(?) pallescens, n. sp.—Glaber ; subdepressus ; linearis ; nitidus ; testa- 
ceus; antennis robustis, brevibus, prothorace vix longioribus, apice fortiter incras- 
sato; capite magno, prothorace vix minore, antice utrinque impresso, postice 
nonnihil constricto; oculis parvis haud prominulis; prothorace obsolete canalicu- 
lato, postice angustato, utrinque foveolato; elytris prothorace parum longioribus, 
stria suturali et utrinque fossa basali profunde impressis ; femoribus crassis. 
Long. 23 m.m. 
This species does not fit naturally into any genus known to me. It will be 
convenient to call it Lispinodes provisionally—noting, however, that it differs 
from that genus, as characterized by Dr. Sharp, as follows—.e., it is much less 
depressed, with the head almost quadrate, and deeply sunk in the thorax, the eyes 
very small and flat, the mandibles resembling those of Prognatha ¢, and the coxz 
as in L. (?) quadratus, mihi. 
The pale unicolorous tint and short antenne of this insect prevent any possi- 
bility of confusing it with any of its Hawaiian allies.
